      This project will investigate and develop improved storage methods for the fuels needed to generate electrical power in places where sunlight is not available. The effort will focus on particularly tailored materials called Metal Oxide Frameworks, or MOFs, that can be used to store methane and oxygen. The methane and oxygen can be reacted in a solid oxide fuel cell to generate electricity, and storing them in a MOF could potentially result in significant mass and cost savings over traditional storage tanks which also require active pressure and thermal regulation. The team will use a number of computational and experimental tools to develop a MOF structure suitable for this application.

      NASA researchers are sending three air quality monitors to the International Space Station to test them for potential future use on the Moon.Credit: NASA/Sara Lowthian-Hanna As NASA prepares to return to the Moon, studying astronaut health and safety is a top priority. Scientists monitor and analyze every part of the International Space Station crew’s daily life—down to the air they breathe. These studies are helping NASA prepare for long-term human exploration of the Moon and, eventually, Mars.

      As part of this effort, NASA’s Glenn Research Center in Cleveland is sending three air quality monitors to the space station to test them for potential future use on the Moon. The monitors are slated to launch on Monday, April 21, aboard the 32nd SpaceX commercial resupply services mission for NASA.

      Like our homes here on Earth, the space station gets dusty from skin flakes, clothing fibers, and personal care products like deodorant. Because the station operates in microgravity, particles do not have an opportunity to settle and instead remain floating in the air. Filters aboard the orbiting laboratory collect these particles to ensure the air remains safe and breathable.

      Astronauts will face another air quality risk when they work and live on the Moon—lunar dust.
      “From Apollo, we know lunar dust can cause irritation when breathed into the lungs,” said Claire Fortenberry, principal investigator, Exploration Aerosol Monitors project, NASA Glenn. “Earth has weather to naturally smooth dust particles down, but there is no atmosphere on the Moon, so lunar dust particles are sharper and craggier than Earth dust. Lunar dust could potentially impact crew health and damage hardware.”

      Future space stations and lunar habitats will need monitors capable of measuring lunar dust to ensure air filtration systems are functioning properly. Fortenberry and her team selected commercially available monitors for flight and ground demonstration to evaluate their performance in a spacecraft environment, with the goal of providing a dust monitor for future exploration systems.

All three monitors are small: no bigger than a shoe box. Each one measures a specific property that provides a snapshot of the air quality aboard the station. Researchers will analyze the monitors based on weight, functionality, and ability to accurately measure and identify small concentrations of particles in the air.

      The research team will receive data from the space station every two weeks. While those monitors are orbiting Earth, Fortenberry will have three matching monitors at Glenn. Engineers will compare functionality and results from the monitors used in space to those on the ground to verify they are working as expected in microgravity. Additional ground testing will involve dust simulants and smoke.

      Air quality monitors like the ones NASA is testing also have Earth-based applications. The monitors are used to investigate smoke plumes from wildfires, haze from urban pollution, indoor pollution from activities like cooking and cleaning, and how virus-containing droplets spread within an enclosed space.

      Results from the investigation will help NASA evaluate which monitors could accompany astronauts to the Moon and eventually Mars. NASA will allow the manufacturers to review results and ensure the monitors work as efficiently and effectively as possible. Testing aboard the space station could help companies investigate pollution problems here on Earth and pave the way for future missions to the Red Planet.

      NASA commercial resupply missions to the International Space Station deliver scientific investigations in the areas of biology and biotechnology, Earth and space science, physical sciences, and technology development and demonstrations. Cargo resupply from U.S. companies ensures a national capability to deliver scientific research to the space station, significantly increasing NASA’s ability to conduct new investigations aboard humanity’s laboratory in space.

      Exploring the unknown and preparing for humanity’s next giant leap really works up an appetite. Thankfully, employees at NASA’s Johnson Space Center in Houston can count on Tina Preyan to help them fuel up and stay focused.

      Preyan is a food service specialist at Starport, a quality-of-life program that contributes to Johnson’s mission by providing employee services and activities that enhance work life and promote mental well-being and physical fitness. Part of the agency’s network of 12 NASA Exchanges — each located at a NASA center or facility — Starport offers everything from group fitness classes to retail shopping, with programs designed to engage, energize, and support the workforce.

      Tina Preyan supports a NASA Exchange display at a Johnson Space Center event. Image courtesy of Tina Preyan Preyan oversees the on-site dining options at Johnson, from its cafés and food trucks to vending machines and mini markets. She helps set the budget for food services, creates monthly calendars of food offerings, schedules vendors and pop-up events, and ensures annual food safety inspections are conducted. She also works with teams across Johnson to order food and related supplies for NASA events.

      “The best part of my job is working in customer service, meeting new NASA workers every day, and making everyone feel welcome and at home when coming to Johnson’s cafés,” she said.

      Preyan has been a fixture at Johnson for the last 19 years. She previously worked at NASA’s Michoud Assembly Facility in New Orleans but transferred to Houston shortly after Hurricane Katrina hit the city in 2005. At Starport, she worked her way up from prep cook to lead cashier and then to lead assistant. She also served as the office’s administrative assistant before transitioning to her current role.

      Tina Preyan poses for a photo with NASA astronauts Jessica Watkins and Victor Glover. Image courtesy of Tina Preyan Preyan has enjoyed meeting many NASA astronauts and Johnson team members and learning more about the work they do. The occasional celebrity sighting is another job perk.

      Preyan is something of a celebrity herself. “So many employees know my name. I am proud of meeting so many people, and the love they give me every day just being here,” she said.

      She was also proud to receive Starport’s Jackie Kingery Award in fall 2024. The award recognizes extraordinary customer service and exemplary dedication to the NASA Exchange mission at Johnson. “It felt amazing to receive this award and know that I am doing a great job in everyone’s eyes,” she said. “I value high integrity and am always willing to help others in the organization.”

      As an Air Force veteran from Spartanburg, South Carolina, Alex Olley now serves as a contract specialist in the International Space Station Procurement Office at NASA’s Johnson Space Center in Houston.  
      Olley joined NASA as a Pathways intern in January 2023 to turn his lifelong goal into a reality—bringing his unique experience in the defense and space industries to support one of humanity’s most ambitious endeavors. 
      Official portrait of Alex Olley.NASA Olley manages the procurement of supplies, services, and research for the International Space Station. His role requires sharp attention to federal regulations and a deep understanding of business practices, all while supporting the astronauts who live and work 250 miles above Earth. 
      “I take great pride in the opportunity that I get to contribute to NASA’s mission each day,” he said. “I’m incredibly grateful for my time here, and it feels like a significant achievement, especially because many of my friends and family have shared how inspired they are to pursue their own goals as a result.” 
      Alex Olley prepares for an Air Force training at Osan Air Base in Pyeongtaek City, South Korea. Image courtesy of Alex Olley A quote shared by Johnson’s director of the Office of Procurement, Bradley Niese, became a guiding principle that has shaped Olley’s NASA experience: “People are the mission, and if we take care of the people, the mission will take care of itself.”  
      That mindset has taught him the value of building relationships within the office, which, he says, often leads to smoother operations and greater motivation. 
      “It’s much easier to be passionate about the mission when you know everyone around you shares the same dedication,” he said. “With such a strong support system, I’ve learned that I can achieve anything, no matter how challenging or confusing the task may seem at first.” 
      Early on, however, he struggled with imposter syndrome. “I felt like I didn’t belong or wasn’t good enough to contribute meaningfully toward our goals,” said Olley. “I overcame that feeling by taking a chance and sharing my thoughts on a work process.” 
      To his surprise, his team embraced the idea—and implemented it. That moment became a turning point, eventually leading to Olley becoming one of the office leaders for a wellness initiative called Better toGether—a creative nod to their office code, “BG.” The program was designed to promote physical and mental well-being in the workplace through activities like NASA Moves, an agencywide challenge that encourages employees to track their steps and commit to at least 20 minutes of physical activity each day. Twice a week, Olley leads brief team meetings focused on desk-friendly wellness tips such as stretches to prevent carpal tunnel and improve posture.
